HOlSTING AND CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 811,671, dated February 3, 1885.

Application filed December 10, 1884. (X0 model.)

To all whom it may concern.-

Be it known that I, JOHN ONEILL, of Milwaukee, in the county of Milwaukee, and in the State of Visconsin, have invented certain new and useful Improvements in Hoisting and Conveying Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to carriers for coal and other elevators, and will be fully described hereinafter.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 is a top or plan view of the same, and Fig. 3 is an end view showing the track in cross section.

A A are the track members, and B are brackets, that are secured to the track members at proper intervals by clamps a, or by any other suitable means. Each of these brackets has hinged to it a bar, B, which forms a buffer when laid across the track, for stopping the carriage at any desired point. The form of these butter-bars is best shown in Fig. 3, both in full and dotted lines. Each bar has two horizontal faces that rest upon a track member, and vertical flanges b, that inclose the track. It also has two projections, 22 b, that receive the wheels of the carriage. Each bracket has also hinged to it a bell-crank lever, C, that carries on its upper end a horizontal rod or bar, 0, while a bar or lifter, G is pivoted to its lower or horizontal arm, and is also pivoted to a bell-crank lever, c. that is in turn fulcrunied to a sill, D, that forms the apex of the track-frame. There are of course as many levers c as there are brackets 13, for by means of the levers 0 and O the buffer-bars are lifted to permit the carriage to continue its travel; and that the buffer-bars may all be lifted from one point, I pivot a horizontal rod, D, to the nyper end of each bell-crank lever c, and this rod extends from one end of the track to the other to within easy reach of an operator at either point.

My carrier consists of two side pieces, F, which form bearings for the axles f of the wheels f.

At about the center of the carriage, and near its top, a rod, 9, is passed from one side piece, F, to the other, and from this red two bars, 9, are suspended, their lower ends being provided with beveled headcatches. Guides G are also suspended from the bar 9, their lower ends being curved and the extremities thereof secured to the side pieces by bolts h.

H is the cable by which the carriage is drawn over the track. The end of this cable is secured to a. rod, I, that extends from one side piece to the other, and then the cable eX- tends under the sheave l of a block, 1 which latter is provided with a hook for catching under the bail 7c of the bucket K, and from under sheave l the cable extends over another sheave, I and thence to'the drawing-power.

L is a lever that is pivoted to one side of the carriage, and L is a bell-crank lever that is pivoted on the front axle ot'the carriage, and is connected with lever L by a link, Z. A spring, Z, is coiled around the axle, and While one end projects through the upper arm of lever L the other is turned over the bar that forms the axis of the sheave l and the torsional action of this spring is such that it will hold the levers L L in the position shown in full lines, Fig. 1, while the carriage is traveling between stations; but when the carriage approaches astation the upper arm ot'lever L will strike an arm, 0, which will cause it to assume the position shown in dotted lines, Fig. l, and throw the lever L down upon the short arm of a catch-lever m, that is pivoted to the hail of the bracket, and as the lower end of this lever normally rests in a catch on the side of the bucket the depression of its upper end will cause the lower end of lever m to disengageitselffrom this catch and permitthe bucket to dump. The block 1 has lugs t 2 project ing from its sides, and when it has been drawn high enough up to permit the levers L and m to come in contact these lugs will have passed over and beyond the hooks of bar 9, which will hold the block in suspension until the carriage is drawn back to a loading station, and when this occurs the beveled head 19 ot' a lever, 1?, will pass under the rod or bar O of the lever (J at that station, and this rod or bar will be confined between the shoulder of head 12 and the upper arm of another lever, q, that the lever P is pivoted to by cross-bar The lower arm of lever q is connected by a cross-bar, q, and links (1 with the bar 9, so that as the wheels of the carriage reach the buffers b the rod or bar will strike the upper arm of lever q, and cause its lower arm, through its links, .to pull the heads of bars 9 from under the lugs i 4; of the block 1 and permit theblock to fall. Now, 5 that the carriage maybe released after the block has been lifted with'its load, it is only necessary to draw upon the cable H, and thereby lift the block until it raises the long arm of lever P high enough to carry the head of its short arm down out of engagement with rod or bar 0.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is i 1. In an elevator and carrier, a truck having hinged buffers, in, combination with rods and levers for raisingand lowering them, substantially as described.

2. The hinged buffers and their levers, in

combination with a cross bar, C, levers P and q, headed bars 9, and the bucketblock having lugs on one side, as described.

3. The carriage having guides for the bucket-block and headed bars for supporting the latter, in combination with a lever, P q q", and the bar or arm 0 of lever G.

4. The combination, with the bucket and its catch-lever, of the levers L and L and a tripping device, substantially as described.

In testimony that I claim the foregoing I 0 have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of WViscousin, in the presence of two witnesses.

JOHN ONEILL.
